During the process of osmosis a semi-permeable membrane allows

During the process of osmosis, a semi-permeable membrane allows only solvent molecules to pass through it. In osmosis, solvent molecules move from an area of higher concentration to an area of lower concentration across a semi-permeable membrane until the concentration of the solvent is equal on both sides of the membrane. This process occurs in order to equalize the concentration of solutes on both sides of the membrane, and it plays a crucial role in many biological processes, such as the absorption of water by plant roots and the regulation of water balance in animal cells.
